General silencer discussion. If you want to talk about a specific silenced rifle or pistol, it is best to do that in the rifle or pistol section for that brand.
For a while now I've been recommending to customers that if they're going to run their 5.56 can on an SBR AR, then you NEEEEEED to run a muzzle brake QD mount with it (instead of a flashhider QD mount).
The brake will act as a kind of "pre blast baffle" and absorb & redirect a lot of the punishment that suppressor's blast baffle would otherwise have to take on a 10.5" AR.
These pics show just how much punishment the brake absorbs. This brake was brand new and the errosion in the pics resulted after only 300-400 rounds (notice the severe errosion around the first chamber of the brake and there's even significant errosion on the second chamber).
Here's what the blast baffle of the can that was run with the brake looks like (a LOT better than the brake):
And also for comparison, here's a brake off of one of our 12.5" guns (notice how much better it looks than the brake off of the 10.5" gun?):

Actually I think that pic of his blast baffle was taken after he changed to the break but had fired 500 rds with a flash hider and 300 rds with the break.
So maybe if he had used a break to begin with that blast baffle would probably look even better.

Maj, so for this reason, would you prefer the Muzzle Brake over even the BRAKEOUT, at least when used on a 10" range barrel? At what barrel length do you think the BRAKEOUT would offer adequate protection and equal/superior overall performance, since alone (unsuppressed), it offers flash reduction too?

Hey Bryon thats interesting.I am waiting on the Form 3 for the YHM Phantom 556 QD and am going to use it on a 10.5 SBR AR15.
Doe's YHM offer a QD Muzzle Brake that will work on my Phantom?
I will not be doing any FA...can't afford those.
I have already put a QD on with some Rocksett too..
I might want to use the Phantom on my 16 inch sometimes too....
On my YHM i was looking at the YHM website and the YHM Brake QD is not to exotic looking as the one at top Bryon showed.Don't look like it
would offer much blast control. http://yankeehillmachine.com/store/product382.html
I'd also like an 18T break in standard AR threading (for the M4-1000 and 762SD). Hopefully when AAC moves into their new huge space they will have more machines and time for this.
I wonder if one could construct a generalized mount with a "sacrificial blast baffle" that has 1/2x28tpi threads on the end and would fit inside any screw-on can?
Been hearing this for years about the Ops cans whenever someone would ask for an FH mount. I have the brake mount on the gun where the can lives and the A2 mount on the gun where the can is pretty much never mounted.
IIRC Steve from ADCO had some pictures of blast baffles comparing FH mounts to brake mounts.

The YHM brake isn't really a brake - it's still just a flash hider (unfortunately). Not every manufacturer offers true muzzle brakes for their cans (AAC is one of the few that does).

For an SBR, that will see heavy use, I would prefer the brake over the Brakeout. The brake has two chambers, so it's like getting a "pre-pre-blast baffle" and a "pre-blast baffle" all in one! The Brakeout is still better than a traditional flash hider, as it offers the built-in brake, with one chamber.

Your shooting schedule will make a HUGE difference. You have to shoot pretty quickly/heavily to get that kind of errosions (shooting in matches, serious training or FA will do it).
Light, recreational plinking isn't as hard on your kit.

Major, is there not 2 separate chambers in the yhm break similar to the aac break or is it open inside like a flash hider?
Its hard to tell from a side view in the pic but I was thinking it had 2 chambers but I'm not sure.
Just wanted to know before I ordered one.
Also primary weapons systems makes a 556 break for the yhm suppressor but it only has 1 chamber.

Well i was somewhat concerned about this errosion on the
YHM 556 Phantom i have coming so i wrote to YHM and asked them about it. I asked if the Muzzle brake QD has a chamber in it and concern for errosion in the blast chamber, they wrote back this which is interesting.
"Sir,
Thank you for your interest in our products. The YHM-5M2-QD Muzzle Brake is open inside like our Phantom Flash Hider QD mount. It however does not surpress any muzzle flash like the Phantom QD Flash Hider Mount. It does work very well as a muzzle brake. All our sound suppressors come with a lifetime warranty so do not worry about internal erosion on your suppressor. If you ever have a problem you may send it back to us and we will repair it at no charge to you other than the shipping charges back and forth. We have never had any erosion problems internally with any of our suppressors. Just be sure to clean the suppressor at the recommended intervals of 1000-1500 rounds and you should have no troubles. There is no need to unnecessarily worry about internal erosion on your sound suppressor."
